With continuous R or T thread, the bar can be connected by the coupling.
Features:
1) It is made of high-strength steel by rolling, and the material conforms to GB/T 3077 "alloy structural steel";
2) The R-type hollow bar is produced with a left-handed wave thread, which uses a large pitch standard thread. The thread shape conforms to ISO 10208 "rock drilling tool - left-handed wave thread" and ISO 1720 standard, and can be combined with a corresponding nut, coupling. , drill bit, adapter, etc.
3) The T-type hollow bar is produced with a left-handed large pitch trapezoidal thread, and it can be assembled with nut ,coupling, drill bit, adapter, etc.
4) Surface treatment requirements such as galvanizing, epoxy and double anti-corrosion can be selected according to the conditions of use;
5) The length is usually 3m, 4m, 6m;
6) If the customer has special requirements for the diameter, length, thread or surface treatment of the rod, it can also be customized.
Applications:
It can be used as a drill pipe when drilling, and can be used as a grouting pipe during grouting. It can be used as a reinforcing rib after installation.
Advantage
1) High strength and quality material is selected, the hollow bar has high strength and plasticity;
2) The hollow structure is used to make it more resistant to bending and shearing than solid bar of the same cross-sectional area;
3) The inner hole of the hollow bar can be used as a grouting passage;
4) The bar is processed by rolling to process the continuous thread, which can be used for any cutting or be connected by coupling for a longer length, and can be used in a small space.
5) The full-length continuous thread can have better adhesion to the cement layer, it can be used as strong support  for tunnels and rock slopes.
